134 Key points about lighting Five questions to ask yourself when choosing a headlamp for your needs 1. Does the energy management of my headlamp suit my needs? Most Petzl headlamps have constant lighting (regulated headlamps). These headlamps ensure stable lighting performance for a pre-determined period of time. This way, the user knows that neither the luminosity nor the lighting distance will decrease during this period. When the energy source is almost depleted, the headlamp still has enough reserve power to allow the user to complete the operation under way, or to change his location. 2. Is the energy source appropriate for my frequency of use? 3. Are the different lighting modes appropriate for my professional activities? Petzl headlamps function with regular batteries or integrated rechargeable batteries, depending on the model. Each type of energy source corresponds to a user profile: - regular batteries are best for occasional use, but their cost ends up being greater over time - integrated rechargeable batteries are designed for more regular or intensive use They are more practical: the headlamp is always ready to use. They free the user from any battery management issues. These headlamps end up being more economical over time, and more ecological Petzl indicates the different lighting modes available for each headlamp. These modes correspond to specific conditions of use: close-range work, moving around, seeing at a distance.
